}- private key 생성을 DB에 생성한 시퀀스를 자동 할당되게 처리하려고 했다.
- 그래서 @Id 어노테이션이 있는 변수에 private key 할당을 어떻게 할 것인지 설정했다.
- 에러 메시지의 제일 하단에 << The increment size of the [seq_board] sequence is set to [50] in the entity mapping while the associated database sequence increment size is [1]. >> 란 메시지가 있다.
- 메시지를 번역하면 Entity로 할당하는 시퀀스 할당 값은 50이고, DB의 시퀀스는 사이즈는 1씩 증가하는 사이즈란 걸 알 수 있다.
- JPA에서 할당하는 시퀀스와 DB에 생성된 시퀀스가 증가 값이 달라서 생기는 현상이 에러의 원인이다.
에러 해결
- SpringBoot 에서 제공하는 JPA의 시퀀스 증가 값과 DB의 시퀀스 증가 값이 똑같이 증가되게 설정하면 된다.

}- 클래스 위에 @SequenceGenerator 추가 후 설정 값에 allocationSize를 정해준다. allocationSize는 메모리를 통해 할당할 범위 사이즈를 지정하는 값이다.
- 50씩 증가 값이 1씩 증가가 되게 지정했다. 에러를 해결할 수 있다.
